What you’ll do
- Elicit business and technical requirements working with the various stakeholders during the requirements gathering phase.
- Author both high level and low level design documents to support Telco services, including presenting such designs for internal technical and stakeholder sign off.
- Perform audit, analysis and propose solutions for migrating from one platform or design to another, providing support for testing and fulfilment teams.
- Own software/hardware selection, perform bug scrubs and security vulnerability assessments and work with test and implementation engineers to review test plans, defects, test reports, MOP and change tickets.
- Participate in vendor selection by providing technical requirements into RFP documents and by conducting technical evaluations including Technical Proof of Concept testing.
- Steer network elements’ feature roadmap by working closely with strategic technology partners for software release planning, budget submissions and providing inputs for business case preparation.
- Drive platform improvements, enable automation and implement new solutions that enable DevOps capabilities and support the business strategy of building once and deploying multiple times.
What you’ll bring
- Requirements-to-Design Translation – Proven ability to translate complex business and technical requirements into clear, implementable network designs, explicitly documenting assumptions, constraints, trade-offs, and justifying design decisions against alternatives.
- High-quality Design Documentation & Technical Authority – Strong technical documentation skills, producing high-quality HLDs using Confluence or similar wiki-based tooling, and acting as a technical authority: constructively challenging sub‑optimal designs and influencing decisions.
- ISP Subscriber & BNG Expertise – Deep experience with ISP subscriber technologies including IPoE (DHCPv4/DHCPv6), PPPoE, L2TP, RADIUS, and stateful/stateless BNG redundancy models.
- Core IP/MPLS & VPN Architecture Design – Deep understanding of telco network architectures with proven experience designing IP/MPLS networks using IS‑IS, Segment Routing, MP‑BGP, LDP, advanced HQoS, and Layer 2/3 VPN technologies including EVPN, T‑LDP, VPLS, and IPv6.
- Automation & Configuration Management – Solid understanding of Python, Ansible, and Git-based configuration management, with the ability to design scalable, repeatable automation to support network deployment and change.
- Telemetry & Operational Assurance – Experience defining telemetry requirements and KPIs to support operational assurance, fault investigation, and capacity planning across metro and core networks.
- Packet-level Network Behaviour – Strong understanding of packet‑level behaviour, including TCP/UDP, MTU and PMTUD, and encapsulation/overhead impacts across access and core networks; able to interpret relevant standards (e.g. RFCs) and validate behaviour through packet-level inspection.
- End-to-End Technical Ownership – Ability to own technical solutions end‑to‑end, including software/hardware selection, bug scrubs, security vulnerability assessment, and collaboration with test and implementation teams on test plans, defects, test reports, MOPs, and change tickets.
Good to have skills
